The acronym knowledge is for the forums, not the card list 
Your card list will be exactly what I'm looking for soon, but first I have to learn the card text of all the cards.
Done!
I'm surprised no one answered this sooner: The basic answer is that there is never any "snapshotting", and all modifiers are always re-evaluated. There are definitely sticky situations, but they have to do in what order you evaluate various modifiers.
Doesn't Scholar have a couple of cards that might apply? Like do X damage where X is the number of non-hero targets out. I think the question is, on a card like that if there are six targets out when you start, but you kill some along the way does X stay six or does it decrease. I believe it stays six, but I'm not basing that off of anything.
The Scholar's cards wouldn't have to do a recheck for X because of how they work. The one I believe you are thinking of is Grace Under Fire. It deals X damage to one target where X is the number of non hero targets in play. He would only need to check once before dealing the damage. He has two other cards with an X value to calculate from "Get Out of the Way" and Know when to turn Loose. The first heals him X for every target he damaged and the second is based on how many cards he discarded. So for all of his cards with X on it there should only be a need to calculate once.
Yeah, I'm just going to pop in and agree DISAGREE that there is no snapshotting. All actions are adjusted as they occur, as needed.
Huzzah for massive, increasing waves of Checmical Explosion damage!
Is that how we decided it worked?
If people are concurring there's no "snapshotting", that's (inadvertenly) how people are saying Checmical Explosion works.
Far be it for me to disagree with the masses. (also, it's an awesome visual, the heroes look on in horror at the rising tide, scrambling to get high enough to escape the destructive wave. The Matriarch, unaware of the impending danger, sends her fowl in to attack the heroes, only for them to fall prey to the acid sea fast approaching, their twisted bodies fuel the surf, propelling it to an even greater height, one no one is safe from...)
Wow, I hadn't paid enough attention to the wording of the Checmical Explosion. I think that's a wording error on the part of >G, but I do like the visual.
I thought it was the number it cards destroyed this way, meaning the vats.
Er, yes, Official Ruling time. Che(c)mical Explosion deals damage equal to the number of Vat cards destroyed.
Chemical explosion still "snapshot" (meaning a fixed number independent of future game states). It's X is dependant upon how many Vats it destroys in its destruction sequence, and it only destroys Vats once, so any future game state won't be able to change it in the first place (unless more vats get played/destroyed during the destruction sequence obviously).
It's X was never dependant on vat destruction, read the cards literally, not for intent has been the rule for Sentinels in almost every discussion here, but now Checmicals is errataed so it no longer works that way, huzzzah for me getting something changed!
Yeah! Cards now work the way I always played them!
I couldn't believe that it didnt' say "this way" on the card, I would have sworn it was there.
You mean "+3" of course.
